<p>A fluid assembly and a method are provided. In one embodiment, the fluid assembly is insertable into a container holding a first fluid to be supplied to a diagnostic instrument and comprises a first element, a second element, and a first conduit fluidly connected between the first element and the second element such that the first fluid in the container moves through the first conduit towards the diagnostic instrument. A second conduit containing a second fluid is fluidly connected between the first element and the second element. A pressure transducer is fluidly connected with the second conduit such that the second fluid is bounded within the second conduit by the first fluid and the pressure transducer. The pressure transducer monitors pressure of the second fluid to indicate a volume of the first fluid in the container.</p> |
